Testnet not working right now?

[arosca]

For the past 2-3 days I have been unable to send or receive any transactions on testnet. I tried two different Android clients (Tesnet3 and Mycelium) and 3 different machines running Armory/bitcoind on different networks. One of my friends also has this issue.

I suspect I cannot connect to other peers and that's what causes the problem. According to http://blockexplorer.com/testnet blocks are getting processed though.

Is anyone aware of any issues? Any ideas on how I could troubleshoot further?

That seems to be the problem, thanks! I added one of these seeds as the trusted peer to Testnet3 on Android and I'm connected now.

However, I haven't been able to get Armory to work. I tried all of the following in bitcoin.conf with no success:

seednode=95.85.39.28:18333
seednode=95.85.39.28
addnode=95.85.39.28:18333
addnode=95.85.39.28

(one line like that for all of the seeds you provided)

Looking at the bitcoind logs, entries like the one below worked (bitcoind is up to date with the latest block). However, Armory doesn't start up for testnet.

addnode=95.85.39.28

Looked into this a bit further. In https://github.com/bitcoin/bitcoin/blob/master/src/chainparams.cpp there are 6 hardcoded seeds for the main network:

        vSeeds.push_back(CDNSSeedData("bitcoin.sipa.be", "seed.bitcoin.sipa.be"));
        vSeeds.push_back(CDNSSeedData("bluematt.me", "dnsseed.bluematt.me"));
        vSeeds.push_back(CDNSSeedData("dashjr.org", "dnsseed.bitcoin.dashjr.org"));
        vSeeds.push_back(CDNSSeedData("bitcoinstats.com", "seed.bitcoinstats.com"));
        vSeeds.push_back(CDNSSeedData("bitnodes.io", "seed.bitnodes.io"));
        vSeeds.push_back(CDNSSeedData("xf2.org", "bitseed.xf2.org"));

Whereas testnet only has 2 seeds:

        vSeeds.push_back(CDNSSeedData("bitcoin.petertodd.org", "testnet-seed.bitcoin.petertodd.org"));
        vSeeds.push_back(CDNSSeedData("bluematt.me", "testnet-seed.bluematt.me"));

Both of which appear to be down as of May 20, 2014.

Still, I don't understand why this would bring the testnet client down. Doesn't it keep a list of previously connected peers?

arosca, it does for me, maybe there is a timeout period after 3 days or something like that.

Does anyone know how much RAM does a testnet bitcoind use after a few days?

The memory footprint is minimal. All data is stored on disk (in Berkeley DB files).

On my machine (Windows) it uses about 100MB (constant--does not increase over time)
